What is the reason you warm the plug?
-

Blue indeed.

Just acquired it. The saw is full of gunk so it looks like it ran with the coil but the serial number got me. That and it not running with petrol down the inlet bypassing the carb.
-
So even with petrol dripped in the carb it won’t start. It has spark but the ignition coil is 510 11 57 02 serial number this on paper is the wrong coil. Is the timing screwed and I need a new coil or should this coil work and it is a different problem? Compression is fairly good but I have not tested it with a gauge.
-
Gone and done it now. Got a 372. Has anyone swapped the high top for a low top and are flogging the high top bits? Or wanting low top bits and have high top bits?
-
Thank you for all the advice and the piston. The 346 ne is running great. I need a new doer uper. Something bigger.
-
It’s been sat now for a good 2 hours and not a drip. Only happened when it was running. The pipe to the bar might be slightly blocked or the pump is playing up. There was oil on the bar but not loads. I reckon it might be the pipe to the bar.
-
I’ll run it in properly tomorrow. Had it idling for 10 minutes and periodically blipped the throttle for a few seconds. I thought it might have been the metal cover that wasn’t putting enough pressure on the two sides of the pipe work that sandwiches the oil pump end. Where exactly would I put the o ring or the liquid gasket?
-
With a bit of carb adjustment the 346 runs great. Not cutting anything because I want the new ring and piston to bed in. However it is leaking bar oil like a sieve.
-
curiosity. Don’t worry I’m not a firewood snob.
-
Willow in the background. All the timber in the forefront is the same stuff though. It didn’t have the typical birch style bark but obviously brown like most of the cherry trees I’ve seen.
-
I was given a load of limbs and sections of trunk for firewood. But what tree did it come from? American holly was my thought. Light weight timber.
-
eould that make it around 1000psi?
-
Under the spark plug must be ridiculous at wot. Completely useless information but still interesting. Someone must know. I’ll ask Jeeves.
-
This test got me wondering. What sort of pressure and vac are developed during use in the crank case? Must be less that the usual 10psi test surely.
-
no bubbles whatsoever on the pressure and no drop on the vac test.
-
Leak test on 346 rebuild went well.

346

Desperate for a manifold clamp. The metal snap ring that secures the boot to the cylinder. Anyone selling one? Tried all the usual sellers on line and non in stock.
-
That is where I saw it. It’s 12 inch limbs mainly that I asking for. Obviously the bigger stuff gets done kneeling with as short a bar as I can get away with.
-
Black and white of it is no then. And it’s all to do with spinning that long chain. Thanks for the replies.
-
hence the question about a long bar
-
Definitely not trolling, I wanting to understand why it’s such a no no. I get using a small saw with a big bar for big cuts puts stress on the engine akin to putting a giant propeller on a small outboard. But does pulling a long chain on its own stress the saw? The logs I get are dumped on the floor so once they are cut up they get split and stacked. Putting them in a horse sounds like another job and one my back wouldn’t be particularly enamoured with.
-
Just wanted the mechanical side of the reason why. Cheers.
